Ilya Leoshkevich 3940daff12 Introduce can_vec_cmp_compare_p 
This is the same as dcd2ca63ec ("Introduce can_vcond_compare_p
function"), but for vec_cmp.  The reason it's needed is that since
5d9ade39b8 ("IBM Z: Fix PR97326: Enable fp compares in vec_cmp")
and 4acba48590 ("IBM Z: Restrict vec_cmp<m><n> on z13") s390's vec_cmp
expander advertises that it supports floating point comparisons except
signaling ones on z13, but the common code ignores the latter
restriction.

gcc/ChangeLog:

2020-11-25  Ilya Leoshkevich  <iii@linux.ibm.com>

	* optabs-tree.c (vec_cmp_icode_p): New function.
	(vec_cmp_eq_icode_p): New function.
	(expand_vec_cmp_expr_p): Use vec_cmp_icode_p and
	vec_cmp_eq_icode_p.
	(vcond_icode_p): Use get_rtx_code_1, just to be uniform with
	vec_cmp_icode_p.
	* optabs.c (unsigned_optab_p): New function.
	(insn_predicate_matches_p): New function.
	(can_vec_cmp_compare_p): New function.
	(can_vcond_compare_p): Use unsigned_optab_p and
	insn_predicate_matches_p.
	(get_rtx_code): Use get_rtx_code_1.
	(get_rtx_code_1): Version of get_rtx_code that returns UNKNOWN
	instead of asserting.
	* optabs.h (can_vec_cmp_compare_p): New function.
	(get_rtx_code_1): New function.

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
